Which of the following is a technology-based way to monitor physical activity? logging exercise on a fitness app measuring distance by stride length tracking movement in a spiral-bound journal verbally counting seconds and repetitions

The correct answers are: logging exercise on a fitness app and measuring distance by stride length.
Tracking movement using a spiral-bound journal is an effective method to track physical activity but it does not use any technological equipment. This applies also to verbally counting seconds and repetitions. On the other hand, when you log your exercise on a fitness app, you use your mobile or other portable device and your physical activity is saved in the fitness application. Similarly, fitness applications are used to measure the distance you walked or ran if you provide them with your stride length. They do so by multiplying the number of steps that they measured by the length of your stride.
